To al whom it may concern.-

Be it known that I, HANs HOHNER, a citizen of Germany, residing at New York city, Manhattan, county and State of New York, have invented new and useful Improvements in Harmonicas, of which the -following is a specification.

This invention relates to a harmonica of novel construction, and more particularly to an improved construction of the sound-chamber and the means for connecting said chamber to the body of the harmonica.

In the accompanying drawings, Figure 1 is a side view of a harmonica embodying my invention; Fig. 2, a longitudinal section thereof on line 2 2, Fig. 3; Fig. 3, a cross-section on line 3 3, Fig. 2; Fig. 4, an end View, and Fig. 5 a longitudinal section of amodification.

The cell-block a of the harmonica has the usual reeds 0/ and lateral wind-openings o The back of cell-block or projects into an approximately U-shaped shell I), made, preferably, of wood and having converging sides I), which extend partly over the sides of block a. In this way there is formed a soundchamber at the back of the instrument that communicates with the Wind-openings at both sides of the cell-block. The forward edges of sides I) are rooved to receive the rear edges of lip-guar s 0, flanking the front of body a and attached to the latter by screws 0. To each end of cell-block a is secured by screws d a flanged end plate d, having a sound-opening d alined with the sound-chamber. Plates d embrace the right and left ends of shell I) and serve to lock the latter to the duces a rich tone, and is not liable to be broken during ordinary use.

What Icla1m is 1. A harmonica provided with a cell-block, a shell inclosing tne back thereof, and end plates secured to the cell-block and engaging the shell, substantially as specified.

2. A harmonica provided with a cell-block, a U-shaped shell inclosing the back thereof, and flanged perforated end plates secured to the cell-block and engaging the shell, substantially as specified.
